Asynchronous N-Layered Division Multiplexing (N-Ldm)

Layered Division Multiplexing (LDM) is a novel non-orthogonal multiplexing access (NOMA) technique, based on power allocation techniques, which has been recently included in the ATSC 3.0 Digital Television Terrestrial (DTT) standard. In the recent literature, the LDM capabilities have been studied just for the two layered case, mainly when one of the layers is targeting mobile/indoor services and the other one high throughput programs. The main objective of this paper is to extend the study of multilayer LDM potential applications to communication paradigms not analyzed so far. First of all, a study of the N-layered theoretical capacity is presented, and after that, new application scenarios that will take advantage of this case will be presented. Finally, several practical simulations to confirm the aforementioned theoretical results will be discussed.
